1DC is about $4K on BH
-
Already announced, highlights include 5 axis IBIS and new LSI front-end which offers "significant increase in sensor readout speed" for stills and video.
With new menu design of course.

This is currently the best LED manufacturer:

the violet chip products easily beat everthing else on the market right now including ARRI in terms of light quality and color accuracy.

4K @ 60Mbps is not good at all, DJI should give an option of selectable bitrate from low to high 100-200Mbps

From owner and operator of the Canon 16-35 f/2.8 (version 1), I can attest that it works on the 70D and the 7D mark 2.
A bit noisy, but it works... its no STM or nano USM...
It's not officially supported though:

Why should v1 not be supported by DPAF? Can you point out where did you read it.
I have lens much older than the v1 (introduced December 2000) that works perfectly fine like the 85 1.8 (July 1991) with DPAF.I have and use regularly the 16-35 II for 4k video (1.3crop) and is quite good, for photos or 1080p the corners are ok but not great, the new one seems better.
It is a good point to consider also the 16-35 F4 IS, personally I would prefer to have the 24 1.4 II + 16-35 F4 than only the new 16-35 III (about the same cost). I have the 16-35 II and the 24 1.4.In Switzarland you can find many on the local ebay at around 800-900 usd, I would never pay 850 for the I version. As soon as there are III on the market the II will drop even further in price.
Canon has a list of DPAF compatible lenses.
Your 85 1.8 is supported.
-
Only version II and III support DPAF.
Version III has significantly better optical quality than version II.
Buy what you can afford.

You need to look at "Screen", not "Print", "Print" DR takes into account the SNR increase as a result of scaling down 30MP to roughly 8MP.
At base ISO100, 5D IV has raw DR of 12.6EV.

The 1DX II is very clean in the shadows (as is the C300 II with the latest firmware: amazingly clean).
Not as clean as 1DC/1DX according to my test.

His speech pattern and body language changed when confronted about the lack of C-log, it clearly suggests elevated stress and anxiety, which implies that he didn't know the actual reason behind the lack of C-log, and he was making up an explanation on the fly in front of the camera.

Actually with low shutter speeds, capturing mpegs from video on 1dx2 can give to much motion blur. I use ND filter it sometimes, but only expensive Tiffen filters do not colour in my experience. its also a problem if you take still and video with the same camera, so I also ignore it quite some times.
shutter speed too low results in too much motion blur on any camera, not just 1DX2.
Also expensive Tiffen/Schneider all have visible colour tint, the best one is ND made by Breakthrough Photography, or True ND from Mitomo Japan.
-
you know, some CGI shots in blockbuster films intentionally add some chromatic aberration to make the shots look more realistic
-
There is nothing right or wrong about it, it's all down to personal preference. For shots with little motion 1/4000 shutter is totally fine, also if it looks too jarring you can add motion blur in post.

Bloody hell Andrew, you've done it now.
I've been following the 1DX II ever since release - ticks a lot of my boxes. But my interest faded with no presence of C-log. I'm big on grading and I absolutely love it, so this now seems interesting to me. Footage I've seen shot in standard profiles looks like it's wrapped in a shiny sheet of plastic.
I use my A7SII the most at the moment. I enjoy using it, however the poor battery life and non-working white balance does my head in. As does the crop in 120fps and the vacancy of 4K 60p, and the low bit rate. Plus the stills - I have EF lenses so I haven't got great stills capability with the A7SII.
With my A7SII, I also have the official clip-on monitor, the Zeiss 24-70mm and 6 batteries - so a great chunk of value here! (If I happen to sell it all).
The DPAF is very interesting (I constantly film fast moving subjects such as rock vocalists going nuts) and high quality 60p is an absolute must. I'm always filming talent who have to look amazing and flawless on camera. So I'm thinking the 1DX II could potentially be a better fit.
Question is to current users: what is the 120fps like? This is what worries me, as Canon don't have a great history of slo-mo. Is there lots of aliasing? Moire? Detail? Noise? Artefacts?
check here:
Also bear in mind that picture profiles cannot replicate real C-log highlight roll-off and colour science.

EOSHD C-LOG
In: Cameras
13 minutes ago, Dan Wake said:Hi @Andrew,
Does your C-Log maps the colors of the "Canon LOG" other than the gamma curve?
thx
No, the colour science and highlight roll-off are not replicable with picture profiles. If you observe Andrew's comparison pic, you will notice the colours are mapped differently on real C-log, and not just a saturation difference, red is less orange and blue has less magenta. Adam Wilt did a comparison between C-log colour science and Alexa colour science, there were some similarities.

In 24p is rolling shutter skew the same as in 60p or more?
That's a bit of a concern / question mark for me.
The 1D C does very good 1080p. The full frame 1080/24p is very nice - not as soft as the 5D Mark III.
The Super 35mm 1080p is high level and the HDMI 1080p when set to 4K is oversampled from the 4K sensor output, so even better.
Does the 1D X Mark II do all of this and more?
Any samples of the 1080/24p full frame to upload so I can take a look at them? Doesn't have to be anything special just a few seconds of a shot at infinity.
Good to hear! How many hours of 4K 24p can you shoot on one battery?
How are the focus racks during a shot when you touch the screen and the AF is set to rack on the slowest / most natural setting - do they look human or do they look a bit stiff and robot like?
FF HD on 1DC/1DX II up to 30p has higher horizontal resolution, vertical resolution is about the same as 5D3. 1DX II 60p and 120p are the same 5D3 quality.
1080p HDMI output in 4K mode on 1DC/1DX II is 2x2 pixel binned, not oversampled.
On 1DX II, 4K mode has consistent rolling shutter at all frame rates, about 16ms.
1DC is the only Canon DSLR that can record internally or stay standby in liveview non-stop for 12 hours (with enough power supply and storage). All other cameras including 1DX II and 5D4 stop recording or exit liveview every 30min. This is important to consider if you do long events.
11 minutes ago, gt3rs said:1/125 is the minimum shutter speed. 120fps is conformed to the camera framer rate 24,25,30 or 60 also no audio. Max record time at 120fps is 7 minutes.
That's partially incorrect I'm afraid, 120/100fps recording gets conformed to 29.97fps or 25fps depending on NTSC/PAL settings, only these two framerates are available when shooting 120/100fps.
38 minutes ago, Andrew Reid said:Thanks a lot DBounce.
Would be interesting to see the same shot in both 24p and 120fps.
Does compression hold up ok at the higher frame rate with motion blur (try a whip pan)... What is the minimum shutter speed you can use at 120fps? Is it a continuous 120fps like the RX100 IV or is conformed in-camera to a standard frame rate?
Higher framerates in HD over 30p are ALL-I compression only, the bitrate scales linearly at 180Mbps for 60p and 360Mbps for 120p, compression artifacts are very rare.

It's too bad there aren't any commercially available Super Resolution sharpening algorithms available (use aliasing information to actually improve resolution). That would be another solution.
When the 5D Mark III came out in 2012 everyone online complained about how soft it was. This video showed that with a little post sharpening and very sharp lenses it was usable:
It's now 2016 and Canon still has the softest 1080p for DSLRs (except perhaps the 5DSR). It still takes some post work to make look decent, however the PDAF makes it almost a toss up between something like the A7S II which is very sharp but has almost useless AF. The C100 II is really the best bet for those looking for decent 1080p, good skintones, and PDAF for a decent price. For slomo Sony is currently the best bang for the buck.
5DS R uses a combination of line-skipping and pixel-binning to read its huge pixel count, the resulting strong aliasing made it appear sharp. But it's still problematic.

Canon 1DX II, Video Mode, EOS Utility 3
All settings can be changed (did not see a visible difference for Fineness and Threshold while watching the Live View on the computer).
Canon 1DX II, Picture Style Settings for Fine Detail
Fineness and Threshold not present.
I haven't done detailed testing for in-camera vs. post-only sharpening (edge convolution, unsharp mask etc.), however the in-camera sharpening looked OK for this test. For slomo on the 1DX II I'd stick with 4K60p if quality is paramount, else 120 could be used for very short shots, and/or close ups along with Neat Video (aliasing, noise), post sharpening, and added film grain. If PDAF isn't needed, the A7S II is much better at 120fps and skin tones can match well enough using Canon reference stills (A7S II settings: Slog2 + SGamut3.cine, +12 sat. etc.).
I tried that a while ago, EOS utility seems to be a bug, it allows you to change the parameters but only strength affects the final image. It's the same video sharpening effect in all previous DSLRs, large radius with obvious edge halo. I just turn it off to 0.

I tested using EOS Utility 3 and it allows changing Strength, Fineness, and Threshold. Fineness & Threshold changes didn't make any visible changes; setting Sharpness Strength to just right of center on any picture style looks the same as the default Fine Detail.
In video mode if you go to PP settings, fineness and threshold will be greyed out. Only strength is available, same effect as previous DSLRs

To get the best detail 1080p out of the 1DX II: use the Fine Detail picture profile with Contrast at -2. Skintones are still a bit waxy: use a little film grain to improve. Some aliasing will occur on fine detail, Neat Video might be able to help there. I tested this at 1080p 23.98 IPB and 119fps ALL-I on the 1DX II (needs a bit more post sharpening- still fairly soft even with Fine Detail picture style). Also tested the A7S II at 119fps- far more detail and usable DR, much lower noise, though does look more video-like vs. the Canon straight out of camera.
Fine detail does not work in video mode, it returns to traditional sharpness setting with no control over sharpening radius and threshold.

I did say the pre-5D3 use line skipping (pixel binning horizontally, pixel skipping vertically) This has been posted online and tested by others.
You said it's 3x3, suggesting both horizontal and vertical binning.

Canon said in several interviews that the 1DX Mk2 was a replacement for both the 1DX and 1DC. When I pointed this out months ago many hear countered, saying the Canon repsaid that said this did not know what they were talking about. All I can say is you might be waiting a long time for a camera that may never materialize. The 1DX MK2 is far from perfect. But in 4k mode it can produce some really nice images. My hope is that Canon would fix the 1080p and give us log. I can see no excuse not to.
Btw: I opened a ticket with Canon on the 1080p. No reason it should look like standard definition.
1DX II is clearly not a broadcast camera, it does not have to comply to industry quality standard (lines of resolution, colour sampling, bitdepth etc. in 1080p). Canon can do whatever they want to keep the cost down and to keep the camera cool and reasonable battery life.
Plus, the 4K mode downscaled to HD is likely going to be approved by EBU for HD Tier 1 use, 1DC and XC10 were approved a long time ago, and as far as I know remain the only DSLRs capable for broadcast use.

From my experience with using Magic Lantern, and understanding of Canon cameras either do:
Canon 5D Mark IV/1Dc/1DX Mark II 4K:
1x1 (4K center crop)
Canon 5D Mark II/7D/T2i/70D and other 1080p Canon cameras released until 2014 (except the 5D Mark III):
3x3 (pixel binning horizontally, pixel skipping vertically, slight upscale) moire/aliasing/scaling artifacts
Canon 5D Mark III/IV/1DX Mark II/7D Mark II/80D 1080p:
3x3 pixel binning - 5d Mark III and most other Canon cameras since 2014 (better moire/aliasing and ISO performance than using pixel skipping)
- 5D Mark III (1920x1080 effective) sensor resolution chosen to avoid upscaling (5760/3=1920)
- 7D Mark II/1DX Mark II: 1824x1026 effective upscaled to 1920x1080
- 80D: 2000x1125 downscaled to 1080p (my guess)
- 5d Mark IV: 2240x1260 downscaled to 1080p (my guess)
Canon 720p Modes:
3x5 (pixel binning horizontally, pixel skipping vertically)
The Canon 5DS(r) is probably using 3x3 pixel binning:
2880x1620 resolution downscaled to 1080p (which happens to be the exact resolution of the Arri Alexa!)
hahaha, you overestimated Canon, pre-5D III cameras use line skipping, there was no 3x3 binning at that time.
5D3 uses large group pixel bins of 5x5, resulting a 1152x648 RAW bayer, which then gets upscaled to 1080p, that's why it has about 600-700 lines of resolution
similar thing happens to other Canon cameras.
The best HD image from Canon DSLR is 1DC in S35 mode, which I've detailed in another post, it resolves near 1000 lines.
A 1824x1026 RAW bayer would be sharp as f***, with resolution easily exceeding 1000 lines.
A7sIII - Get ready?

All modern Sony sensors use copper interconnect, it has nothing to do with BSI which is a photosite architecture, Sony calls it Exmor R, R for Reverse. It's only used on pixel-dense sensors like A7R II, RX100 series and most mobile phone sensors.
BSI on a alleged 15MP FF sensor is just scientifically and commercially unnecessary.
